First and foremost, cannabis is entirely legal in my state, and it's proved to have many, many medicinal uses far beyond recreational use. It's pain relieving properties surpass any pain salves over the counter as well as prescription. I've discovered this with personal use on serious osteo and rhuematoid arthritis. I've also used it to relieve pain in certain of my older chickens with good success. I was reading that it may also have anti-fungal properties as well. I mixed some dried leaf into their morning ration of fermented feed, and I will be using it directly in and around the affected hens' vents. I'm charting new territory here unless I hear from others who've tried this treatment with positive results. Or negative results, as the case may be. Please respond!
